BD3805F

www.DataSheet4U.com BD3805F Audio ICS Sound processor for car audio BD3805F The BD3805F is a sound processor developed for car audio. High S/N and low distortion rate of parametric equalizer can be composed without an external capacitor. Pop noise when switching volume, fader, mute and tone gain can’t be heard due to the integrated soft switching circuit. zApplications Car audio, Mini component stereo, Micro component stereo, DVD, TV zFeatures zExternal dimensions (Unit : mm) 1) Noise when switching, attenuation of fader and fader, and gain (middle bass and treble) can be reduced by soft switching circuit.. 13.6±0.2 2) Perfect due low current consumption (Typ.12mA) and energy saving 22 12 design due to Bi-CMOS process. 3) Available for Rear Entertainment System due to I2C BUS control that can use two ICs at maximum. 1 11 0.15±0.1 4) Noise occurred through tone pass can be reduced (5µ Vrms) DataSheet4U.com 5) External components reduced largely by incorporating external filter 0.1 0.4±0.1 1.27 due to the switched capacitor circuit technology. Bass, treble and middle can be controlled freely. 6) Integrated Ground Isolation Amplifier input idea for external stereo SOP22 signal input. 7) SOP22 package is adopted Pins for voice input and signal output are located together to arrange the flow of signal in a same direction. It enables to make layout of board pattern easier and to save space of the board. 7.8±0.3 5.4±0.2 1.8±0.1 0.3Min. zAbsolute maximum ratings (Ta=25°C) Parame...
